Does anyone know the sizes of the human heart, a large molecule (e.g. protein) and a small molecule (e.g. amino acid)? I've been looking on the internet for ages and i can't seem to find how large they are.
Thanks

the heart is approximately the size of a fist (big man with big fist: big heart, small child with small fist, small heart) a protein: albumin, hydrated (in an aqueous solution with enough coordinated water-moelcules arouond it to feel good) has an approximate diameter of 7nm and it's polypeptide chain is approximately 300 amino acids long (sic the size of an amino acid). There bigger and smaller proteins than that, and not all are globular. Fibrillary proteins are longer but thinner.

Because there is not just one size of each. An adult heart is larger than a child's heart. The molecules are also different sized.
